New study reveals impact of plastic on small mammals, as four out of seven species identified as ‘plastic positive’

Researchers investigating the exposure of small mammals to plastics in England and Wales have found traces in the feces of more than half of the species examined. The densities of plastic excreted were comparable with those reported in human studies.

Pioneering recycling turns mixed waste into premium plastics with no climate impact

Only a fraction of the material that could be turned into new plastic is currently recycled. Researchers have now demonstrated how the carbon atoms in mixed waste can replace all fossil raw materials in the production of new plastic. The recycling method is inspired by the natural carbon cycle and could eliminate the climate impact…

Strategies beyond recycling to bolster circular economy for solar and battery technologies

In a new comprehensive literature review, researchers have discovered that alternatives to recycling may have untapped potential to build an effective circular economy for solar photovoltaic (PV) and battery technologies. These alternative strategies, such as reducing the use of virgin materials in manufacturing, reusing for new applications, and extending product life spans, may provide new…

Reassessment of greenhouse gas emissions from African lakes

A new study reassesses emissions of carbon dioxide and methane into the atmosphere from African lakes. While it was previously assumed that these lakes were significant carbon dioxide sources, it has since been discovered that they really emit very little carbon dioxide but a lot of methane, adding to the emissions burden.

Lessons from the past: How cold-water corals respond to global warming

Corals react to changes in their environment. This is true for tropical as well as cold-water corals and includes, among others, changes in temperature, salinity and pH values. Researchers have now investigated how warmer temperatures occurring as a result of climate change are affecting cold-water corals. For this purpose, they examined in detail how these…

Earth-abundant solar pixels found to produce hydrogen for weeks

Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks — according to new research. The findings could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.

Textile filter testing shows promise for carbon capture

Researchers found they could filter carbon dioxide from air and gas mixtures at promising rates using a proposed new textile-based filter that combines cotton fabric and an enzyme called carbonic anhydrase — one of nature’s tools for speeding chemical reactions.

How a knee replacement impacts the planet

Researchers are quantifying the effects of healthcare on the environment, specifically the particularly waste-heavy and energy-intensive specialty of orthopedic surgery. The researchers reviewed existing literature and found that while data is still sparse, efforts to reduce the carbon footprint of orthopedic surgery could make a huge impact.
